Iceland's volcanoes could power the UK: but at what cost?

Comment

Making up some order of magnitude numbers, were 600 geothermal installations at a £20m each able to provide power for towns of population of 100,000, (60 million people in all) the bill would be of the same order as the raw material cost of the proposed cable. If these guesstimate figures are anywhere near the mark, it would suggest that local geothermal power would be cheaper the imported variety. Add to that the strategic and economic advantages of distributed local power generation, and the advantage increases.
